LIQUID-LEVEL GAUGE.

Application filed June 25, 1924. Serial no. 722,497.

My invention relates 'to the class of de-- andwhich includes a sump 7 to the side of 55 vices employed for determining ti*om out which my improved gauge is attached. This s de observation the level of liquids within gauges comprises at body 8 having an inlet receptacles, and an obyect of my invention, port 9, a low level, outlet port '10, high among others, is the provis on of a single level outlet port 11 and an ntermediate controlling elementof a devlceby means-of leveloutlet p0rt12. A high level discharge 60 whichdiiierent levels 01 the liquid maybe spout 18 and an intermediate'level discharge determined 111 a convenient, manner, my nnspout: 14 pro ect tromthebody, said spouts prove-d gauge being especially designed for being connected respectively with the high use indetermining the level of oil in the and intermediate level outlet ports 11 and crank case of an automobile engine. 12, and as shown in Figure a of the draw- 65 One form of gauge embodying my invenings.

It the valve be turned one step Figure 5 is a top view with the high level contra-cloclnvise the way '16 will be caused spout br k n ff, to register with the ports 9 and 12 and the A common practice at the present time fiowof 011 w ll be permitted out of the interindetermining the il level in an automomedlate SpOU'E- l4, providedthe Oll level in bile engine is to provide two stop cocks, one the cranlr case 18 high enough to cause flow 20 located above the other 011 the rank case out Of SalCl SpOHtS. In this last position Of andproviding flow of oil from the interior the V ve oth the ports 11 and 12 are in of such case. With sucharrangement howommun cation with the inlet port 9, but ever, if th 11 l l b b t th t this is lmmaterial, as this position of the k hi h i a ti f to l l, th valve will ordinarily take place only after 35 lv f b t-h kg u t b Opened t 1 it has been learned that the liquid will not termine that fact.

portion of the crank case of an automobile I desire to have it understood that the deengine of ordinary form and construction vice shown is only illustrative and thatthe invention may be carried out by other means and applied to uses other than those above set out.

I claim 1. A gauge comprising a body having a liquid inlet port and a plurality of outlet ports, a fixed di charge spout communicating with each of said outlet ports, with the discharge outlets of the various spouts located at different elevations, and a single device for controlling communication; between the inlet port and the various outlet ports.

2. In a gauge, the combination with a reservoir, of a gauge body having an inlet port to receive liquid from said reservoir at a predetermined low liquid level, said body also having an outlet low level port below the low liquid level and a plurality of higher level outlet ports above said level, a

fixed discharge spout communicating with each of the higher level outlet ports vvith the discharge outlets of the various spouts located at different ele'ations corresponding respectively to predetermined liquid levels of the reservoir desired to be indicated, and a single device for controllingcommunicating between the liquid inlet eolniection and the various outlet ports.

3. A gauge comprising a body having a liquid inlet port and a plurality of outlet ports opening out of the body at substantially the same level, fixed discharge spouts each communicating: at one extremit; with its respective outlet port, the free extremities of the various spouts being located at difi'rent elevations, and means for controlline communication between the inlet port and the various outlet ports.
